It was intended to be released on September 29, 2011 as part of Super Robot Wars' 20th Anniversary but got pushed back to November 29, 2012.

Developed by the same team behind Super Robot Wars Original Generation Gaiden, the game uses high-energy, dynamic action for the in-game battle sequences.

The Twin Battle System from previous Original Generation installments, where two adjacent units can combine into a single squad, which can then attack simultaneously, will return.

During the ending of the final episode of the anime, a small teaser was shown, also advertising the DVD release of the series.

[citation needed] After a yearlong hiatus, the developers showed the game's third PV as well as the final release date.

The first one includes the Blu-ray box set of Super Robot Wars Original Generation: The Inspector alongside a new casing designed by Ebata Risa.

[8] A downloadable expansion pack for the game called Super Robot Wars Original Generation: Dark Prison (スーパーロボット大戦OG ダークプリズン, Sūpā Robotto Taisen Ōjī Dāku purizun) was released in Spring 2014.

The first print versions of Super Robot Wars Original Generation Infinite Battle also includes the expansion pack in a limited basis.
